Discussion

Hurricane Michael made landfall yesterday in the Florida Panhandle as a “major” category 4 system and today it will accelerate to the northeast as a tropical storm. Its tropical moisture field will interact with a strong cold frontal system advancing towards the east coast and the result will be some heavy rainfall today and tonight in the DC-to-Philly-to-NYC corridor. In fact, periods of rain and embedded thunderstorms into later tonight may end up resulting in a couple inches of rainfall in much of the I-95 corridor. By early Friday, post-tropical Michael will be working its way into the open Atlantic and the strong cold front will push through our region. Winds will pick up on Friday out of the northwest and much cooler and drier air will pour into the Mid-Atlantic region. For the first time this season, temperatures will drop into the 40’s for overnight lows beginning late Friday night/early Saturday morning and then again over the weekend. A fast-moving upper-level disturbance could throw a few showers our way late Friday night and Saturday before a dry, cool day ends the weekend on Sunday.
